At, ballpark, 1000 times the clock frequency. It’s a pity we do not how to connect such a large number of tiny cores in a way so that it can perform meaningful work. One hurdle is that, even ignoring the insane amount of connections needed, it would not be possible to connect each of those cores to each other one because their address spaces are so tiny.

Every so often someone reinvents the transputer, and it turns out not to be quite as good as mainstream multi-core CPUs, but the wheel must turn.

Cerebras built the wafer scale engine so I'm not sure what you're pitying.

yeah, i have the notion that a grid would be good enough
